The Green Death - Production

Production

During the recording of the footage of the maggots around the quarrysite, several of the maggot props were in fact inflated condoms (some inflated with air, others with water). The colliery used for filming was Ogilvie Colliery near Glamorgan, while Global Chemicals was the RCA International factory in Powys. The script required the Doctor to state that the maggots have "thick chitinous skin". Pertwee asked Producer Barry Letts how to pronounce the word, and Letts, unaware of the term, told him to pronounce the first syllable "chit", rather than the more correct "kite". Two days after Episode 4 was broadcast, Letts received a letter consisting simply of the words, "The reason I'm writin'/Is how to say kitin ."

This story marks the final appearance of the "howlaround" title sequence introduced in 1970. It also is the last appearance of the logo introduced in Spearhead from Space until the 1996 television movie. The 1996 version of this logo has been used for marketing purposes by the BBC since that time, and is still used for the "classic series". The closing title graphics are run upside down and backwards on Episodes 2, 5, and 6. The reasons for this are unclear and range from saving time rewinding the film to trying something new with the titles, as they would not be used again.
